A new naming scheme for the upcoming Zen 4 server processors alias Epyc had already been suggested, and now it is slowly becoming visible. According to this, the socket SP5 processors will be located in the new 9000 series, the number four at the end stands for the fourth generation Epyc.
Socket SP6 becomes Epyc 8000, Socket SP5 Epyc 9000
AMD Epyc 7003 aka Milan will be followed by AMD Epyc 9004 in the future. But that's not all, an AMD Epyc 8004 will also appear. While the 9000 series relies on the large SP5 socket, the 8000 models will rely on the smaller SP6 socket. Among other things, the memory interface is halved in this case and there are also a few other limitations. In the end, this product simply addresses a different market below the absolute spearhead. Because the tip has it all this time.
Up to 128 cores are placed in the SP5 socket in the form of Bergamo, those special cloud processors with customized Zen 4C cores. Regular Zen 4 cores are available in the form of AMD Genoa, with a maximum of 96 cores available here. Exactly one digit explains which processor it is in the end, in the revised naming scheme, namely in the second place. But this is exactly where there are the first small stumbling blocks: In socket SP6, the same number can be in the second position for AMD Bergamo instead of Genoa in socket SP5.
First models planned
The naming scheme combined with the first models also reveals how large the model range could be. From eight to 128 cores, everything is included, and there is reserved space in the numbering for the next generation with even more cores. The regular processors will be followed by the X variants, i.e. those with a stacked L3 cache, which will be released next year. The letter “P” still stands for 1-socket versions, the number 7 in the third place in the designation together with the abbreviation F for models with extra high clock frequency. Statements of this kind are ultimately not new, Intel has been trying to do this for years in their respective Xeon series.
AMD wants the Officially introduce the server platform. At the presentation of Ryzen 7000 at the beginning of the week, AMD explained that the company had secured large quantities of wafers and that it did not expect any problems for the desktop in this regard. Since the CPU die is identical, some chips should also be lost for initial deliveries from Genoa. Bergamo with adapted cores should only follow a few weeks and months later, probably in early 2023.
